  2. 1. Evidence for adaptive variation at the genes coding for cytosolic phosphoglucose isomerase (PGIC) in Festuca ovina L

    Author : Yuan Li; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 3-D protein structure; purifying selection; positive selection; cDNA sequences; local adaptation; alvar grasslands; Festuca ovina; Phosphoglucose isomerase; PgiC loci; SNPs; nucleotide polymorphism; horizontal gene transfer;

    Abstract : The gene (Pgi) encoding the enzyme phosphoglucose isomerase (PGI) which plays a central role in the main pathways of carbon metabolism has been shown to be of adaptive significance in a wide range of different species. Earlier studies of enzyme electromorph variation in the grass Festuca ovina suggest that variation in cytosolic PGI (PGIC) may be involved in the adaptive response of F. READ MORE

  4. 2. Unveiling Mechanistic Details of Macromolecular Interactions: Structural Design and Molecular Modelling of DNA-Protein Systems in Their Active State

    Author : Anna Reymer; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; molecular modelling; intercalation; homologous recombination; DNA; ruthenium II polypyridyl compounds; human Rad51;

    Abstract : Molecular structure is fundamental for understanding mechanisms of molecular interactions. This applies not least to understanding biological function: every biological cell, whether bacterial or human, is an immensely complex system of thousands of molecules that exist in constant motion and interaction with each other.

  5. 3. Structural studies of sugar binding proteins

    Author : Sanjeewani Sooriyaarachchi; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Binding proteins, which are themselves non-enzymatic, play an important role in enzymatic reactions as well as non-enzymatic processes by providing a binding platform for the specific recognition of particular molecules. For example, periplasmic binding proteins play a vital role in nutrient uptake in Gram-negative bacteria. READ MORE

  6. 4. Defense-peptides against mycobacteria

    Author : Charlotte M A Linde; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Antimicrobial peptides; NK-lysin; granulysin; PR-39; Mycobacterium;

    Abstract : Several members of the genus Mycobacterium can cause serious infections in both man and animal. One of the world's most serious infectious diseases, tuberculosis, is caused by the pathogen Mycobacterium tuberculosis. Specific defense to tuberculosis/mycobacteriosis is dependent on the individual's ability to mount a proficient immune response. READ MORE

  7. 5. Expression and Function of Human and Plant Aquaporins

    Author : Maria Agemark; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aquaporin; water channel; overexpression; Pichia pastoris; AQP8; AQP5; SoPIP2; 1;

    Abstract : The aquaporins (AQPs) belong to a family of water permeable membrane channels found in virtually all living organisms. Thirteen isoforms of mammalian AQPs are found, whereas in Arabidopsis thaliana 35 genes encoding AQPs are found. The AQPs are distributed in different organs, cell types and in different subcellular membranes. READ MORE
